The LT

performance available to date for monolithic operational

amplifiers: 2.5nV/

√Hzwidebandnoise(lessthanthenoiseof

a 400

Ωresistor),1/fcornerfrequencyof2Hzand60nVpeak-

to-peak 0.1Hz to 10Hz noise. Low noise is combined with

outstanding precision and speed specifications: 10

µV offset

voltage, 0.2

µV/°C drift, 130dB common mode and power

supply rejection, and 60MHz gain bandwidth product on the

decompensated LT1037, which is stable for closed-loop

gains of 5 or greater.

The voltage gain of the LT1007/LT1037 is an extremely high

20 million driving a 2k

Ω load and 12 million driving a 600Ω

load to

±10V.

In the design, processing and testing of the device, particular

attention has been paid to the optimization of the entire

distribution of several key parameters. Consequently, the

specifications of even the lowest cost grades (the LT1007C

and the LT1037C) have been spectacularly improved com-

pared to equivalent grades of competing amplifiers.

The sine wave generator application shown below utilizes the

low noise and low distortion characteristics of the LT1037.
